1 Vortex Crossfire II 3-9x40mm Rifle Scope – Best Affordable Scope for 300 Win Mag

We begin with a very well-received optic from Vortex. This is their Crossfire II 3-9x40mm model.

What’s the model choice?

This scope comes with a choice of three different reticles. Shooters can choose between the standard V-Plex or Dead-Hold BDC reticle, which come in at the same cost.

Alternatively, you can plump for the more expensive (but still keenly priced) Illuminated V-Brite reticle. If going for the latter option, removable lens covers and a cleaning cloth are also included. All reticles are SFP (Second Focal Plane). In terms of power, this is from a CR2032 battery that offers 150 hours of life.

Built to withstand heavy ammo…

Other specs of the three models are the same, and highlights include Variable magnification of between 3-9x, a 40mm adjustable objective lens, a 1-inch main tube, and capped windage and elevation turrets. These turrets allow shooters rapid zero-reset and give the ability to achieve highly repeatable shots.

The exit pupil is between 4.4-13.3mm, and the linear field of view at 100 yards varies between 12.6 and 34.1 feet. It also includes a fast-focus eyepiece, which helps in timely target acquisition as well as reticle focus. As for eye relief, this is an acceptable 3.8- to 4.4-inches.

Crisp, clear imaging…

Constructed using aircraft-grade aluminum, the Crossfire II 3-9X40mm optic is built to last. Vortex has designed the scope to ensure it is fog proof, waterproof, and shockproof. The fully multi-coated lenses also ensure a crisp, clear image across its magnification range.

The included sunshade works to enhance viewed images during sunny day shooting. However, shooters can be assured this optic also performs well in low light conditions.

Some dimensions and specs…

The scope is 12-inches in length, 1.84-inches high, weighs in at 15 ounces, and is ring mounted. Adjustments are MOA with click values in 0.25 MOA steps, and wind/elevation travel is 60 MOA. Parallax is 100 yards with focus range of 100 yards to infinity.

6 NightForce SHV 4-14×56 .250 MOA Riflescope – Model C520 – Best Premium Scope for 300 Win Mag

Our final best high quality scope for 300 Win Mag use comes from NightForce. Put simply; they are a force to be reckoned with in the riflescope world.

An objective lens to be reckoned with…

NightForce have built this SHV (‘Shooter Hunter Varminter’) scope to withstand the harshest, toughest conditions while still delivering ultimate precision. The featured objective lens works by determining resolution, light transmission, and exit pupil size. More on these specs shortly, let’s first consider its construction and dimensions:

Shooters will be buying into a scope machined from solid bar stock 6061-T6 aluminum alloy. NightForce then combines lenses of top quality that afford real precision. This combination will withstand consistent and repeated recoil from the largest calibers and is shock as well as temperature proof.

Perfect adjustments…

Variable magnification is between 4 and 14x; it has a 30mm main tube and the quality 56mm diameter objective lens. The non-illuminated SFP reticle is MOAR (there is also an illuminated model available). Adjustment click value comes in 0.25 MOA steps, and adjustment range is 100 MOA.

As for parallax, this is side adjustable and comes in from 25 yards and infinity. The exit pupil is between 3.6-12mm with field of view at 100 yards between 24.9- and 7.3 feet.

This is seen as being particularly beneficial when it comes to hitting smaller targets over longer ranges.

Best Scope for 300 Win Mag Buying Guide – What to look for?

Best Scope for 300 Win Mag Buying Guide

There is no doubt that .300 Win Mag rounds are most popular when it comes to hunters and larger game. However, competition shooters and various law enforcement officers are increasingly using this caliber. To get the most from these heavy-hitting rounds, a quality scope will certainly assist.

So, here are three major factors to take into account when choosing an optic that suits your style and applications…

How far are you Targeting?

The .300 Win Mag affords shooters an excellent opportunity to hone their long range shooting skills. This means a scope that gives the ability to reach such distances needs to be a priority. While it is possible to accurately reach distances in excess of 1,000 yards with this round, that may well be stretching things for many shooters.

Having said this, if your intention is to improve distance shooting accuracy in a gradual manner, then a scope with long magnification is a definite recommendation.

Versatility is the key…

An example is the fact that for 1,000 yard targeting, shooters should look at 10x+ magnification. But, keen hunters will not always require such long distance ability. With this in mind, going for variable magnification from 3x upwards gives flexibility as well as longer range ability.

Another targeting factor to consider is the scope’s ability to perform in low-light or during dawn/dusk hunting. Regardless of the distance, if you cannot clearly see targets at these times, you are very unlikely to hit them! This is where quality scopes with good light transmission lenses really are worthy of attention.

Durable Reliability

This relates mainly to hunters who expect to get down and dirty. Those into this type of hunting already know (and anyone new to the sport will soon find out!) that conditions and environment are not always ideal. That last ‘ideal’ comment has to be the understatement of the year! But let’s face it, for committed hunters, this is a big part of the thrill.

Rough handling over differing terrain and weather conditions that often have a mind of their own is a given. This means a robust, durable, and reliable scope is needed. Water, fog, and shockproof features should be seen as a minimum requirement. Your chosen scope must also stand up to anything you throw at it and function with continuous accuracy.

Those shooters whose main use will be for competition or down the range will not find such durability as important. However, protection from heavy recoil and constant use is still a must. The final important factor to consider is a scopes ability to hold zero and do so consistently.

Reticles and Focal Plane

Crosshair reticles certainly have their place, but they are not ideal for longer range shooting. Those shooters looking to get the best results from the use of .300 Win Mag ammo need more. This should be in the form of a patterned reticle that comes with either Mil-Dot, MOA, or BDC markings.

Yes, this type of reticle can increase complications of use, but with time and practice, they are more than manageable. They also give a huge advantage when it comes to making the vital adjustments necessary for those hard-to-achieve long range shots.

FFP or SFP?

As for where the reticle sits, your choice is either FFP (First Focal Plane) or SFP (Second Focal Plane). FFP reticles change size in proportion to your target when zooming in or out. A key design advantage of this is that it will significantly assist effective BDC (Bullet Drop Compensation) and windage estimations. This is regardless of the magnification level you are on.

When it comes to a SFP reticle, this remains the same size at all magnification levels. This type of static reticle means any BDC markings are valid only at one magnification. This means that SFP reticles are not as effective for longer range shooting as FFP reticles. However, they can still be used to good effect and tend to be a lot less expensive than FFP reticles.

So, what is the Best Scope for 300 Win Mag?

Shooters who favor the .300 Win Mag round will maximize its hard-hitting and longer targeting ability by also using the best quality scope for 300 Win Mag ammo. While all six of our choices fit the bill, we would highly recommend the…

Leupold VX-3i 4.5-14x50mm Side Focus Riflescope

This optic is of proven quality and guarantees 100% waterproof, fog proof, and shockproof use.

You have a choice of two non-illuminated SFP reticle models, both of which come with side focus functionality. This means that you do not need to move your head from your weapon when making those crucial adjustments. Variable magnification comes in between 4.5, and 14x so mid to long-distance accuracy is yours. The scope is also equipped with a 30mm main tube and a top-quality 50mm objective lens.

Shooters will benefit from crystal clear daylight images as well as additional low-light and dawn/dusk shooting time. This is thanks to the company’s Twilight Max Light Management System.

We feel this optic could well become a hunter’s best friend! And, to top things off, you are buying into peace of mind with Leupold’s lifetime warranty.

Happy and safe shooting.
